Mechanical complications would be defined as all those complications that involve the prosthesis such as abutment screw loosening, fracture of the veneer material, fracture of the crown framework, abutment screw fractures, and implant fractures. The category of biologic complications will include the complications that involve the soft tissues ex. fistulas, suppuration, bleeding, gingival inflammation, and soft tissue dehiscence.
